Solvent effect on the debromination/dehydrobromination of bromo-damascone

The dehydrogenative synthesis of beta-damascenone from beta-damascone via the related allyl bromide intermediate was studied in depth. The requisite dehydrobromination thereof was found strongly solvent system dependent. Under respective conditions, the product was identified as dehydrogenation-derived a, 4-alkoxy-derived b and 4-oxo-derived c, accordingly. In addition, the conversion from b to a was successfully accomplished, thereby offering an alternative access (with one step more) to reach beta-damascenone. Copyright

Use of Bromine and Bromo-Organic Compounds in Organic Synthesis

Bromination is one of the most important transformations in organic synthesis and can be carried out using bromine and many other bromo compounds. Use of molecular bromine in organic synthesis is well-known. However, due to the hazardous nature of bromine, enormous growth has been witnessed in the past several decades for the development of solid bromine carriers. This review outlines the use of bromine and different bromo-organic compounds in organic synthesis. The applications of bromine, a total of 107 bromo-organic compounds, 11 other brominating agents, and a few natural bromine sources were incorporated. The scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc. has been described briefly to highlight important aspects of the bromo-organic compounds in organic synthesis.

Recent advances in utilities of active iodine reagents as organo-catalysts in organic synthesis

Since 1990s, the application of organo-iodine reagents as oxidant in organic synthesis went through explosive progress. In early times, most of organo-iodine reagents were used as stoichiometric terminal or co-oxidants in oxidative reactions, which inevitably led a lower atom coefficient of utilization and environmental issues. In this regard, it is very urgent to develop varies of efficient approaches of the catalytic utilization of organo-iodine reagents in organic synthesis. Recently, more and more iodine compounds were used as organo-catalysts for many kinds of reactions, which were revolutionary progress for iodine chemistry, and could also meet the need of green chemistry. In this review, we presented an overview of catalytic utilization of active iodine reagents as organo-catalysts in organic synthesis and also some successful examples for asymmetric catalysis. We focused on the recent synthetic strategies, applications of organo-iodine reagents and its mechanism as organo-catalysts, and finally gave a perspective of future development.

Orexin research: patent news from 2016

Introduction: The orexin system consists of two G-protein-coupled receptors, orexin 1 and orexin 2 and two endogenous ligands, orexin A and orexin B. It is evolutionarily highly conserved. It is involved in the promotion of wakefulness as well as in anxiety and addictive disorders. In addition, its activation via the Ox1 receptor triggers apoptosis in several cancer cell lines. Dual orexin receptor antagonists are successfully used to treat primary insomnia. The major open questions are now related to the clinical validation of Ox1 selective antagonists. A strong rationale exists for orexin agonism in the treatment of narcolepsy with cataplexy. Areas covered: The patent applications from Thomson Reuters Integrity Database added in 2016 are summarized and discussed together with the most important findings published in the scientific literature. Expert opinion: The large number of patents shows the continuing interest in the orexin receptors as targets. The structural scope covered is narrow. Questions about novelty and inventiveness are evident. The additional information published on X-ray structures on both orexin receptors opens new ways of optimizing antagonists. It might also influence the efforts in the identification of orexin receptor agonists. Being potential treatments for narcolepsy with cataplexy.

Identification of 5-Substituted 2-Acylaminothiazoles That Activate Tat-Mediated Transcription in HIV-1 Latency Models

The persistent reservoir of cells latently infected with human immunodeficiency virus (HIV)-integrated proviral DNA necessitates lifelong suppressive antiretroviral therapy (ART). Epigenetic targeted compounds have shown promise as potential latency-reversing agents; however, these drugs have undesirable toxicity and lack specificity for HIV. We utilized a novel HEK293-derived FlpIn dual-reporter cell line, which quantifies specific HIV provirus reactivation (LTR promoter) relative to nonspecific host cell gene expression (CMV promoter), to identify the 5-substituted 2-acylaminothiazole hit class. Here, we describe the optimization of the hit class, defining the functionality necessary for HIV gene activation and for improving in vitro metabolism and solubility. The optimized compounds displayed enhanced HIV gene expression in HEK293 and Jurkat 10.6 latency cellular models and increased unspliced HIV RNA in resting CD4+ T cells isolated from HIV-infected individuals on ART, demonstrating the potential of the 2-acylaminothiazole class as latency-reversing agents.

Improving Drug Design: An Update on Recent Applications of Efficiency Metrics, Strategies for Replacing Problematic Elements, and Compounds in Nontraditional Drug Space

Drug discovery and development is a complex and lengthy enterprise that suffers from high rates of candidate attrition at all stages of the process. The physical, biological, and toxicological properties of a drug candidate are inextricably linked to its structure, and once a molecule has been synthesized, all subsequent studies along the development path are focused only on assessing and understanding its properties in greater detail. Unfortunately, a full prediction of the biological properties of a molecule from an analysis of its 2- or 3-dimensional structure is currently beyond our expertise. This backdrop mandates that considerable care be taken at the design stage if a molecule is to be successful in testing a mechanistic concept underlying a disease process and to progress into late stage clinical trials and, ultimately, marketing approval. While there are multiple potential causes of candidate attrition, an introspective analysis of drug design practices over the past decade has focused attention on the perception that contemporary molecules are unnecessarily obese, burdened by high molecular weight and excessive lipophilicity. This practice is believed to have its roots in the singular pursuit of enhancing potency during lead optimization rather than adopting a more holistic approach to drug design that gives broader consideration to how structural features affect developability properties. In an effort to provide the medicinal chemistry community with practical guideposts to enhancing compound quality in the drug design phase and which can readily be applied, a series of efficiency indices have been proposed that attempt to define aspects of compound quality in the context of a series of physicochemical parameters. Of these metrics, lipophilic ligand efficiency (LLE or LipE), which provides an index of the dependence of the potency of a molecule on its intrinsic lipophilicity, has been characterized as the most robust metric that has potential for broad-based application. In this review, after describing the background literature behind the derivation of efficiency metrics and approaches to assessing compound aesthetics, synopses of some recent practical application in lead optimization campaigns are presented. However, molecules that fall into space beyond that associated with traditional drug-like properties are an important part of the current and future landscape, exemplified by the summary of direct acting hepatitis C virus NS3 and NS5A inhibitors that have transformed clinical therapy for this chronic disease. While drug development in nontraditional drug-like space is more challenging and the rules for compound quality will be different with much still to be understood, careful and disciplined drug design practices will be an essential element of success.

Chalcones bearing a 3,4,5-trimethoxyphenyl motif are capable of selectively inhibiting oncogenic K-Ras signaling

Ras proteins are small GTPases which regulate cellular proliferation, differentiation, and apoptosis. Constitutively active mutant Ras are expressed in ~15?20% human cancers, and K-Ras mutations account for ~85% of all Ras mutations. Despite the significance of Ras proteins in refractory cancers, there is no anti-Ras drug available in clinic. Since K-Ras must interact with the plasma membrane (PM) for biological activity, inhibition of the K-Ras/PM interaction is a tractable approach to block oncogenic K-Ras activity. Here, we discovered chalcones 1 and 8 exhibit anti-K-Ras activity, and show that the compounds mislocalize K-Ras from the PM and block oncogenic K-Ras signal output. Also, 1 inhibits the growth of K-Ras-driven human cancer cells. Our data suggest that 1 could be a promising starting point for developing anti-K-Ras cancer drug.
